What I'm trying to find out is basically what options there are in order to make the site fit to pass the test. What different drainage options are there etc. I'm under a small bit of pressure to make a decision on the site and having walked around it and checked it out at various times (inc after heavy rain) it did'nt seem at all marshy or boggy.
hmm - disagree - if test holes have water in them then they might be slow draining - do a test yourself - ram a piece of 2X2 in there vertically - pre-mark it in inches - fill it with a few gallons of water and watch the drainage (the actual test is done with pre-soaked holes) - T value is the water level drop over time - I can't remember the formula for T value calc. - have it somewhere - you'll find it on the net anyway - but best to get the report - look at the profile of the test holes - any clay or mottling indicating water holding? If its loose sandy/gravel then OK as long as not fast draining - ultimately if it failed the test it failed the test though ...
